EXTENSION BED.

.Application led April 5,

- to the accompanying drawing.

My1 invention relates to anextension bed and l declare the following to he e full, clear, concise and complete description thereof suilioient to enable anyone skilled inthe art to which it epperteins to make and use the same, reerenceheing had to theaecompanying' drawings in which like reference characters refer to like parts thronghout'the specification.

The object of the invention is to provide an elevating frame for an extension day hed, a, couch or cot, which will be of simple con struction and can be easily and quickly aetnated into elevated position. To this end, the` elevating frame embodies rook members 'adapted to elevate the spring mattress csrried thereon by swinging the pillow rest member of seid frame into upright position. The object Will appear by referring to the drawings, in which:

Fig. 1 is a. perspective' view of an extension day bed, showing the parts in extended position; and auxiliary spring removed;

' Fig. 2 is a detail elevating frame;

Fig. 3 is a detail fragmentary perspective View of an angle guide rail employed for sliding the extension frame on;

Fig. f1 is a detail perspective view of the extension spring used;

Fig. 5 is an enlarged perspective view of e fragment of the extension frame, showing the locking bolt attached et one end.

Referringr more particularly to the drew ings, anV ordinary day bed, couch or cot hed is represented by 3.- having end members 2 and B and adapted to support a spring el. The hed is provided also with guide ways formed by shoulder brackets 5, 5 mounted on each of the end members 2 and 3. whereby to permit the extension fra-me 6 to slide nnder the spring i of the bed, when not needed. Any well known stop device for. limiting the outward movement of the extension with reference to the bed 1 may he used such perspective'view of the w21. serial No. 458,691@

es slide bolts 1G, 10 disposed on either end of the rear side of the exension frame 6 and adapted to engage shoulders 11, l1 formed integral with the shoulder brackets 5. The slide bolts 10 con be dre-Wn free `orf *the shoulders 1l' when it is .desired to remove the extension frame altogether from the hed rzzme--1-. v

Nirhin the extension l'rame 6, there. is mounted s novel rook iframe 15', which comprises the two rock shafts i6, i6 that are journaied in hearings mede ley oonntorsinling holes in the respective sides of the freine (i. Arms i7, i7 and 13, 3 8 are morini/ed in sets upon the rock: shafts i6 and are lined to turn with' said shafts i@ by set screws 20. Each` of the arms i7 and 18 is formed with e curve therein, in order to avoid deed oenter element in the rooie of 'the frame i5, es Well us to stabilize the i'rsme when in upright position. formed with en integral bracket 2i that is disposed substantially in parallel relation tothe erm i8 and are adapted io support at their upper ends e cross piece 22 for :i pillow .resti The upper ends of the arms i? and i8 are connected by the two rods 2li, 2li which unite Esch of the arms 18 is in each instance an arm l? and an arm i8.

The rods 24 are made with their extreme ends bent at right angles v*which pass through' suitable apertures in theupper ends of each of the arms 17 and i8 arranged in sets of two, as above stated and are riveted in plane in. such manner that the ends turn freely in the recesses formed insaid arms i7 end i8, whereby the frame i5 can be moved from its lower to upper position or vice versa, as illustrated bjwthe full and dotted lines in Fig. 2. Rollers A are disposed in the recesses formed in arms 17 and 18 and are adapted to rotate on the ends of rods 24. 9.4, Wnerehy to aid .in reducing friction. VThe roc-k frame 15 carries e demountnhle, spring 30.

The operation of the rock frame 15 is effected, after the extension frame 6 llas been drawn out to its full extent, hy mai'iipnlat-v order to elevate the upper surface of the auxiliary or extension spring mattress 30 even with the upper surface of' the main spring' mattress e to form shed." When foldlt will be noted that te elevate er lower the roel: frame l5, whereby to raise or lower lhe auxiliary spring 30, it is necessary onlv te manipulate the pillow rese The auxiliiary spring will reise amd. lower in the same Vertical plane because ef the guide pins 8l fastened adjacent the 'eur eerners ce the lower part ef sind auxiliary spring frame and edeped ie ride m guide ruige 32 secured near the lower parl; of the. extension frame 6.

The exeeneen' frame G is equipped with ege te zuil m supporting it, when 1n exended position.

mense mounted on seid extension frame, curved arms adapted to rock with said shafts, rods -co'nneeting the upper ends of said arms,

whereby said arms Will move in the same 'erined integral with certain of said arms, whereby te aid in moving said arms in the same clirecton to elevate and lower said mattress.

1n testimony whereof I have affixed my signature.
